Lehmer's conjecture, also known as the Lehmer's Mahler measure problem, is a problem in number theory raised by Derrick Henry Lehmer. The conjecture asserts that there is an absolute constant such that every polynomial with integer coefficients satisfies one of the following properties: • The Mahler measure of is greater than or equal to . • is an integral multiple of a product of cyclotomic polynomials or the monomial , … Lehmer's conjecture, also known as the Lehmer's Mahler measure problem, is a problem in number theory raised by Derrick Henry Lehmer.

NettetThe test. The Lucas–Lehmer test works as follows. Let M p = 2 p − 1 be the Mersenne number to test with p an odd prime.The primality of p can be efficiently checked with a simple algorithm like trial division since p is exponentially smaller than M p.Define a sequence {} for all i ≥ 0 by = {=; The first few terms of this sequence are 4, 14, 194, … Nettet24. nov. 2024 · The proof of Theorems B and A are based upon a result of Bugeaud and Shorey [4, Theorem 2] on positive integer solutions of a Ramanujan-Nagell type equation. This method is applicable only when k is a power of a prime, and thus we can not apply the same in the proof of Theorem 1.1 .

NettetLehmer conjectured that τ(m) 6= 0 [12]. Thus, Theorem 1.2 is a reformu-lation of Lehmer’s conjecture. A homogeneous space of VOA Vm has strength t if Vm is a conformal t-design but is not a conformal (t + 1)-design. We have not yet been able determined the strength of(V♮) m for general m, and so Lehmer’s conjecture is still open. NettetLet q be an arbitrary prime factor of Mn.
